摘要

The objective of this investigation has been the study of metal release during corrosion characterization of Fe2.5Co64.5Cr3Si15B15, Fe3Co67Cr3Si15B12 and Fe5Co70Si15B10 amorphous metallic alloys, used as based materials to create new type for giant magnetoimpedance (GMI) biosensors. Alloy samples were tested in phosphate buffered saline solutions (PBS, artificial biological solutions) at pH 7.4 and 22 degrees C. Individual alloy constituents (Fe, Co, Cr, B) released during the electrochemical corrosion tests, were analyzed by differential pulse stripping voltammetry (DP) using a hanging mercury drop electrode technique (HMDE). In this work, the experimental results obtained are discussed in order to study their corrosion behavior in artificial biological solutions and thus determine their possible use as GMI biosensor prototype materials.
